The Reference Shelf · Doneness, not safety theater

Internal Temperature Chart

USDA pulls one line for safety across thirty-plus cuts of meat, fish, and poultry, but the number you actually cook to is rarely that line. The chart below lays out both, the safe minimum and the doneness most cooks pull at, so you can make the call.

II · Red Meat

Red Meat

Whole muscle cuts of beef, pork, and lamb can be pulled rare to well-done as long as the surface has been cooked. Ground versions need to hit a higher safe minimum because grinding folds surface bacteria through the interior.

III · Poultry

Poultry

USDA targets 165°F for all poultry. In practice, breast meat pulled at 155–160°F and rested carries to safety while staying juicy, the dryness most cooks blame on the bird is usually a thermometer-driven overshoot.

Poultry

Chicken

Doneness Temperature Description
Safe
165°F
75°C
No pink remaining, juices run clear
USDA required minimum - check thickest part

Poultry

Turkey

Doneness Temperature Description
Safe
165°F

No pink remaining, juices run clear
Check both breast and thigh for whole turkey

Poultry

Duck

IV · Seafood

Seafood

Fin fish have a wider doneness window than the USDA chart implies. Tuna and salmon pulled at 120–125°F are still safe when sourced as sushi-grade and held cold; the 145°F line is the conservative target for unknown provenance.

140°F
60°C
Opaque with hint of pink, still moist

V · Safety

Food Safety Guidelines

The thermometer is the only authority that matters. Three things to keep in mind once you have one in your drawer.

Using the Probe

Temperature Measurement Tips

  • Always use a reliable instant-read thermometer
  • Insert thermometer into the thickest part of the meat
  • Avoid touching bone, fat, or gristle when measuring
  • Clean thermometer between uses to prevent cross-contamination
  • Allow meat to rest after cooking - temperature will continue to rise

After the Heat

Recommended Resting Times

Small cuts (steaks, chops)
3-5 minutes
Large roasts
10-20 minutes
Whole turkey/chicken
15-30 minutes

Carryover

Heat keeps moving after you pull

Temperature continues to rise during resting

Small cuts

2-5°F (1-3°C)

Large roasts

5-10°F (3-6°C)

A Note on Limits

These temperatures draw on USDA FSIS safe minimums and the FDA Food Code. Always use a calibrated instant-read thermometer and follow proper food handling practices. When in doubt, cook to the higher line. This guide is reference material, not a food-safety certification.
